“…And this might be due to its ease of design and operation, wide range of available adsorbents, less energy required, flexibility, and cost-effectiveness [ 84 ]. Just like biological and chemical precipitation processes, the adsorption process produces sludge and the regeneration of spent adsorbent is energy-consuming, insufficient, and results in high costs [ 114 ]. Nonetheless, research on the adsorption process is increasing and most adsorbents exhibit high removal efficiency.…”

Purpose: Heavy metals are among the commonest cause of water pollution and impact human health worldwide. Therefore, this study aims to assess the probable health risk (non-carcinogenic and carcinogenic risk) for adults and children that are exposed to toxic heavy metals (Cu, Pb, Cd, Cr, Zn and Ni) through ingestion and dermal contact with dug well water in the locations. Methodology: The hand dug wells serve as sources of drinking water, domestic and industrial purposes. In this study, composite samples from the locations were tested for the presence of heavy metals using Atomic Absorption Spectrophotometer (AAS). The health risk assessments were evaluated. Findings: The results of the HQ values of heavy metals for combined pathways were below the safety level (HQ < 1) for adults, while the HI for children were higher than the safety limit in some stations. The average values of total carcinogenic risk index (CRI) through exposure to drinking water for children and adults were lower than 10−6. Overall, the CRI total through exposure to drinking water for children and adults are within safety level of WHO risk, negating the probability of carcinogenic risk for the children and adults to the carcinogenic elements via ingestion and dermal routes. Recommendation: Appropriate purification, improvement in enlightenment programs and control measures should be implemented to protect the health of the residents in these localities.

“…The literature reveals that very few Se removal studies have been conducted using commercial NF membranes despite their high potential in the separation of anionic contaminants of water in a sustainable way. [ 4,98,99 ] To improve rejection and fouling performance, different functionalized thin film nanocomposite membranes have also been explored. Functionalized membranes exploit the novel properties of nanoparticles such as high surface area, offering a large number of charged functional groups that improve rejection efficiency and selectivity with enhanced flux.…”

“…[ 2 ] Both geogenic as well as anthropogenic activities have triggered water contamination by leaching of selenium akin to contamination of water by lead, iron, arsenic, and chromium. [ 3–5 ] The high solubility of Se in water, together with its wide concentration range, poses a great challenge to the scientific community to remove the leached‐out Se from the precious drinking water. In the rural areas of the developing and the underdeveloped world where underground aquifers are the only source of potable water, such contamination of water by excessively leached out minerals is aggravating the crisis of safe drinking water scarcity.…”

Selenium (Se) is known both as an essential micronutrient for human health as well as a toxic element when consumed in excess. This work endeavours to critically review the existing selenium literature over the period 1980-2021, following a systematic sub-classification into the domains of occurrence, speciation, and existing conventional and advanced technologies, while directing further research towards emerging integrated sustainable recovery strategies.
